Comparative Outcomes and/or Complications Following Ventriculoperitoneal versus Lumboperitoneal Shunts: A Scoping Review

Abstract

Cerebrospinal fluid (CSF) diversion procedure in the form of ventriculoperitoneal shunt (VPS) has been performed for over a century and is a well-established method for treating hydrocephalus. With the passage of time and the availability of better technology, several other CSF diversion modalities developed with variable risks and benefits. Lumboperitoneal shunt (LPS) is a close and safe contestant for the VP shunt procedure and is regarded as an alternative treatment modality for hydrocephalus. The present scoping review followed the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. A literature search for the study was performed on PubMed, COCHRANE, SCOPUS and ScienceDirect (from inception to 7 July 2022). Those studies that were published in the English language with a report on comparison between VPS and LPS for the management of hydrocephalus were included in the review process. Those studies that do not have comparative outcomes, case reports, letters, reviews, preclinical studies, conference reports and non-human studies were excluded from the study. Search results showed 134 records; after removing the duplicates and excluding 12 studies with reasons, five studies were included in the present review. Several complications were described in patients who underwent either VP Shunt or LP Shunt surgery. Although communicating hydrocephalus forms one of the most significant subgroups of patients in neurosurgical practice and VP and LP shunt procedures are also widely performed, the literature review shows limited comparative efficacy. In addition, the reported studies have a broad spectrum of indications, disease conditions and complications with a heterogeneous patient population. To further develop the high level of evidence, there is a need for well-designed prospective protocols to help us develop uniform and practical guidelines. In the present review, we looked into the common complications, including shunt malfunction, shunt infection, subdural haematoma, shunt obstruction and shunt migration between two groups.
